Ase Utra Radien is an over-barrel suppressor that combines light weight and superior sound and recoil reduction. It weighs only 290 grams, but provides net suppression of 29–31 dB on the ear level with a .308 win. These qualities make it ideal for any hunter.

Radien is manufactured from hard anodized aluminium and designed for .223/6.5mm and .30 non-magnum calibers. There are three different color options available so you’ll be able to select a suppressor that matches your own rifle perfectly.

S Series SL5i is the smallest suppressor on the market, which yields a sound level of less than 140 dB at the shooter’s ear with a .308 Win caliber weapon. SL5i is well suited for hunting and shooting on the range. The SL6i series suppressors are designed for heavy-duty hunting rifles.

For those who are looking for more performance, our range can offer the S series SL7i suppressor that offers more suppression in only a slightly larger size. It is a good choice if you are looking for maximum suppression for the .308 Win caliber, for example. S series suppressors come in a large selection of threads, which ensures that the suppressor will suit barrels of various sizes. The various suppressor models of Ase Utra

can be equipped with heat covers. The covers are manufactured from very durable 1000D CORDURA® and Nomex® fabrics. The covers effectively reduce and delay the effect of the mirage from the suppressor. They also assist in removing a hot suppressor from the barrel.


The Ase Utra ECO rimfire suppressor features excellent sound suppression and is intended for both pistol and rifle use. The ECO suppressor is manufactured from aluminium with an anodized finish. The suppressor allows the use of iron sights or low mounted optical sights.

The standard threads available for the suppressor are 1/2” x 20 UNF or 1/2”x28 UNEF. Due to the simple design, the ECO suppressor can easily be taken apart for cleaning and maintenance.

SL4i-SMg Mp5 SL6i-SMg Mp5The SL4i-SMG and SL6i-SMG suppressors are intended for MP5 submachine guns and carbines. The suppressors quick mount to the barrel lugs.

The SL4i-SMG suppressor is very compact, whereas the SL6i-SMG has more suppression performance in a slightly larger size.

The DUAL-Fifty is designed for .50 BMG caliber sniper rifles. The suppressor has a so-called dual structure that leaves room for gas expansion between the suppressor element and the outer shell. The suppressor structure is a completely welded, closed unit.

The suppressor is manganese phosphated. The suppressors come in various threads, which makes them compatible with the most common .50 BMG caliber firearms.


BoreLoCk Hiper and Bird Cage FLaSH HiderSThe Hiper flash hider is an extremely efficient flash hider. The tapered alignment surface before the attachment thread effectively blocks fouling from entering the mounting surfaces and allows for ease of attachment and removal. HiPer flash hiders are available to a variety of weapon types, from .223 Rem up to .30 caliber.

For those seeking a more traditional flash hider solution, we also have a BoreLock bird cage flash hider available in the same calibers.

BoreLoCk Mounting CoLLarThe primary purpose of the BoreLock mounting collar is to enable the user to continue using a flash hider or a muzzle brake that is already on the weapon.

To be compatible with the BoreLock mounting collar and suppressors, the muzzle device needs to be under 22 mm in diameter and have a maximum length of 63 mm.

BoreLoCk .30/.338 and .223/5.56 CaL MuzzLe BrakeSThe two-part design of the BoreLock muzzle brakes provides for secure, simple, and quick installation. No washers or shims required, thus allowing for precise alignment.

Muzzle flash with an Ase Utra HiPer flash hider, M4 carbine with 14.5” barrel.

The BoreLock fast-attach mounting system is our newest generation of fast-attach mounts.

The BoreLock mount provides an easy to operate and secure attachment to many of the common weapon models available. BoreLock mounting suppressors are available from 5.56 mm NATO up to .338 LM caliber.

Suppressors equipped with the BoreLock mount are designated by the letters “BL”.

BoreLoCk Mounted SuppreSSorSThe new DUAL 556/762 series has been specifically developed to have significantly less back pressure than earlier suppressor models. In addition, DUAL provides superior flash reduction. The SL5i/SL7i-BL suppressors offers top performance in two caliber sizes, .30 and .338. SL8i-BL is developed especially for the .300 Blackout caliber, taking into account the use of sub sonic and super-sonic loads.

The sound pressure levels given on this page are tested on measurement equipment especially intended for measuring gunshot impulse noise. The shots have been fired in open terrain, over 10 metres away from any reflective surfaces. Please note that sound pressure levels are affected by many factors, such as the environment, weather conditions, caliber, barrel length, and cartridge.

The B&K 2209 sound pressure level meter used by our company is designed for reliable measurement of impulse noise.
